Specification of Letters Eatent.

Application filed April 17, 16.03. Serial .NmeQQ-MO.

To all whom it may concern:

lBe it known that l[, JoHNH. CHAMBER- LIN, a citizen of the United States, residing at the city of Kalamazoo, county of Kalamazoo, State of Michi an, have invented certain new and usefu Improvements in Window-Screens, of which the following is a specification. v

This invention relates to improvements in window screens. I

The main objects of this invention are;

first, to provide an improved window screen in which the screen is effectively supportedv without providing a full frame therefor. Second, "to provide an improved screen which may be very quickly applied to or removed from the window. Third, to provide an improved screen possessing the above advantages in which the supporting means are so arranged as not to obstruct the window. Fourth, to provide an improved window screen which is readily adjusted to windows of varying dimensions.

Further objects, and objects relating to structural detailswill definitely appear from the detailed description to follow.

T accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, forming a part of this specification, in which:

' Figure 1 is an elevation of a window having my improved screen applied thereto. Fig. 2 is a detail vertical section taken on a -line corresponding to line 2-2 of Fig. 1. Fig. 3 is a detail horizontal section taken on a line correspondin to line 33 of Figs. 1

and 2.. .Fig. 4 is a detail elevation, showing the means for securing the closure strip 22 to the bottom bar 7 of the screen. Fig. 5 is v an enlarged detail section taken on a line corresponding to line 55 of Fig. 2. Fig. 6 is a detail perspective of the attaching means for one end of the upper screen bar.

Tn the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents a window casing of the common construction, having upper and lower sashes 2 and 3, re-

flanges 15 at their upper edges which spective'ly, arranged therein. The screen i is adapted to cover the entire window, that is, both the upper and lower sashes thereof,-it being of substantially the width.

of the window casing so-that it overlaps the outer window stops 5 at each side and er:-- tends from the top nearly to the bottom.

Cross-pieces or bars 6 and 7 are provided for the top and bottom of the screen, the

bar 6 being the top bar and the bar 7 the,

bottom bar. The screen is preferably secured to these bars by means of the clamping strips 8 and 9, and the securing screws 10, which clasp the strips upon the screen. The ends of the bars 6 and 7 are provided with vertical slots 11 to receive the flanges 12 on the supporting'members 13. These supporting members are secured upon the inner edges of the outer window stops, the flanges being arranged, as stated, to engage the slots 11 in the screen bars. The bars are preferably the same width as the window Patented Mar. .1', i910.

stops 5 to permit the window sash being raised or lowered, as may be desired. The upper screen bar is secured u-on its supporting members 18 preferably y means of the retaining plates or members 14, having roject under the bar so that in attaching the bars are slipped on to the flanges and retained thereon by means of the retaining plates or members 14-, the plates being provided with perforations to receive the attaching screws, as 17, see Fig. 2. The lower bar 7 is preferably retained and tension applied to the screen for holding it taut by means of the spring 18 which, is the preferred construction as illustrated, are arranged through the vertical holes 19 in the bars to engage the pins 20, their lower ends being secured to the sill by means of suitable hooks, as 21. effectively secured and tension applied to the screen for holding it in place, and also by this yielding connection, the screens are adapted to windows of varying sizes. That is, it is found, in practice, that window casings which are intended to be of the same dimensions often vary considerably in the same building, and by this yielding attachment for the lower screen bar, no variations The lower bar is thus can be applied-or removed from the bars without removing the screws. These screws have the further advantage of being adapt "ed to hold the closure strip 22 adjustably in an elevated position to leave a. small openin beneathfor drainage or for cleahing.

y improved screen is very economicalto roduce, and is as stated, very quickly and? easily applied. Further, its supports do not obstruct the window, they being quite unnoticeable from the inside of the window, particularly when the window is closed, and further, the screens are quickly attached or detached.

I have illustrated and described my improved screen in detail in the form preferred by me although I am aware that it is capable of considerable modification or variation without departin from m invention, but as these modi cations Wlll. be readily understood by those skilled in the art to which this invention relates, I have not attempted to illustrate or describe the same herem.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: y 1. The combination w1th,a window casing, of a screen; cross-bars secured at the top and bottom thereof, said cross-bars being arranged on the inside of said screen and having vertical slots in their ends; supporting members having inwardly-projecting flanges adapted to engage the slots in sald cross-bars; retaining members having inwardly-projectin flanges at their upper edges arranged be ow the upper crossbar for retaining it on said supporting members; springs for securing the lower cross bar to the window sill, said 3 rings being arranged in vertical holes provided therefor in the bottom cross-bar; a closure strip having vertical slots therein arranged on the inside of the bottom cross-bar; and securing screws for said closure strip arranged in said slots therein.
